fore-wings broad, with the costa curved, and the hind margin 

 not very obhque ; fore-wings about twice as long as broad ; 

 hind-wings rounded, longer than broad. 



I reject the name Cossus as applied to this genus, for it is 

 admitted to be objectionable to employ specific names, which 

 should be inviolable, in a generic sense ; nor do I consider the 

 compromise of Cossus cossus sufficiently elegant to be adopted. 

 Swainson was the chief author who attempted to introduce the 

 practice of taking specific for generic names into Entomology ; 

 but this has been followed in so few instances that they can 

 easily be eliminated. In ornithology and in some other 

 branches of natural history, the practice has attained to such 

 dimensions that it would be difficult, if not impossible, to 

 eradicate it ; but there is no reason why this should not be 

 successfully attempted and carried out in Entomology.
